Where it all began

I went to University of Chicago with Dave on tuesday. As we appraoched the building we had to visit, dave showed me a strange bronze structure like that stood like a monument in the centre of an open area. Thats the first place where a controlled nuclear (fission) reaction was succesfully carried out by Enrico Fermi on December 2 1942 !!

So now I can say if a third world war breaks out... I know I know where it all began ...
